This invention relates to an improved headlight and is olf the type that is described and claim Patents and reflectors of ed in my 1,398, #1,3 l9,6 l-2, issued August 1.7, 1920. less prior patents a central per previous United States issued December 6, 1921,

describe a, reflector with placement relative to so that the upper and 1e rays so that einp.

Thls provides s. non-glsre reflector, that the field above the Wes not pierced ed rays. In.

by direct oi -shs tne previous patents, it was horizontal unis oi the lump rply rellectnecessary :to incline the light bulb and, fun thermore, the light bulb holder was niounted directly on tl plate. i To make bulb holder and pendently to. the

horizontal bulb to the reflective functions of my is the purpose e present invention a. reflector t nt isin: headlamp shells or on it is a reflector oil which may he reudi single unit, suitable forms of reflectors in 1e horizontal partition or the reflector with the lump the partition attached inderefiector and to provide it support and still conform headlamp,

Another objoct of the invention to pro 'vide a device for adj listing the bulb support so that it is accessible from the front and by means of which the bulb can bend retracted and in this W vanced or uy the light centre can.

ht has, not been tampered with after the cial test has been made which is not the case in those types where an adjustment is made from the outside of the shell making it easy for inexperienced ersons to tamper with the focus of the hea light.

To focus this headlight the adjustments can be made without removing. the reflector unit from the shell and while the light is burning. It is only necessary to open or re move the door of the shell and the results of the adjustment can be viewed so that the defects can be seen at once in contrast with the successive lighting and extin ishing of thelamp while adjustments are eing made in the oldway.

In'this form'of headlight it is usual to provide a horizontal partition 23 which is placed to coincide approximately with the plane of the junction line at which the two dissimilar reflecting surfaces are joined. The partition may beheld in place in any suitable way usually by lugs 24- whichcan be inserted through slits in the reflector and then slightly turned to lock the partition in The partition has a small hood or sub-reflector 25 at the front end of an opening 26 which receives the bulb 18, this small re ector 25 preventing rays of light passin e forwar which is the u per alf of the area or field g are zone.

At the rear of the open n shield 27 which is dis used vents rays from the h' flattene portion 13.

26 I strike up a so that it pret source striking the his prevents the flattened portion of the upper reflecting surfa e 0 .from reflecting light in directions apt o cause glare. While this shade or shield is in the preferred arrangement attached to the horizontal plate or partition, it may be ,use a reflector with two dissimilar to serve this purpose. T e partition also serves the useful purpose of shielding either of the two dissimilar reflecting surfaces from much of the'diflused light emitted by the opfosite reflecting surface. The reflection 0 diffused light emitted by the reflecting surfaces themselves is the source of some uncontrolled illumination in directions tending to cause glare in headlamps and the use of a horizontal partition through the s ace encompassed by the reflector unit, re uces the amount of such uncontrolled flux.

It is therefore possible by this invention to reflecting surfaces, the front edges of which are insertible in a circular shell or casing and the rear parts of the reflector or central part of the owl where these reflecting surfaces overlap is so made that both the upper'grefleeting surface and the lower reflecting surface are flat in the same vertical plane so that the two halves coincide at the point of juncture. I

I claim: c

A reflector for headlights which is formed of sheet metal with 'its u per and lower halves desi ed with a diiibrent curvature relative to ti e central axis so that the halves the central portion of the reflector where these halves meet being flattened, a socket for a bulb at the' lower part of the flattened portion, an adjusting means for the socket. said means being accessible at the upper art of the flattened portion and from the ront, and ashield between, the bulb and the flattened portion to prevent rays from the bulb being reflected by 'said portion.
